Quantum simulations with atoms and photons


Cavity quantum electrodynamics (QED) is one of the most powerful frameworks to observe and leverage quantum phenomena. While it has been thoroughly studied for simple quantum systems such as two-level systems or harmonic oscillators, it has only recently become available for complex, correlated quantum many-body systems. In the last years, we have developed systems combining cavity QED with cold Fermi gases. In this talk, I will describe these setups, and some of the intriguing consequences of the interplay of strong atom-atom and strong light-matter coupling. I will then present the use of the cavity to induce long-range interactions between atoms and show our recent results on density-wave ordering and magnetism induced by this interaction. Last, I will outline the perspectives open by the convergence of cavity QED with complex quantum matter, in particular the possibility of programming cavity-mediated interactions at will and the application of these ideas for condensed matter and high-energy physics.



All talks hybrid:

Mixture of on-site talks at the main sites of QuCoLiMa (Erlangen, Mainz, Saarbrücken) as well as online talks. Regardless of where the talks are given, they are livestreamed via Zoom and can be watched from home/office or cooperatively in the following meeting rooms:

- Erlangen: Livestream/Presentation in Lecture hall HF + open sandwiches in the foyer afterwards

- Saarbrücken: Livestream/Presentation in tba

- Mainz: Livestream/Presentation in tba

QuCoLiMa Talks are regular seminars of the collaborative research center TRR 306 QuCoLiMa (Quantum Cooperativity of Light and Matter), where (external) experts are invited to present their work.
